The iceberg, dubbed A-76, measures around 4,320 sq km. Officials say it is 170 km in length and 25 km wide.
The ESA says the iceberg, which is currently the largest in the world, is “slightly larger” than the Spanish island of Majorca. To compare, the agency says the A-74 iceberg, which broke off earlier this year, was only 1,270 sq km.
Photos of the berg were captured by the Copernicus Sentinel-1 mission, which allows for year-round viewing of remote regions like Antarctica.
